Mafia III: Definitive Edition released on PlayStation 4 yesterday for £24.99/$29.99, bundling together the base game and all its DLC packs. That's not a terrible deal, but the thing is, there's a very realistic chance you actually already own the game. Mafia III was a free PlayStation Plus title back in August 2018 and since its story DLC has been made available for free to everyone, your copy will have been automatically upgraded to the Definitive Edition if you added the original game to your library.
Even if you've only just picked up a copy of Mafia III, you can still take advantage of this deal. The Stones Unturned and Sign of the Times expansions are both completely free, while the Faster, Baby! DLC should join it shortly. For some reason, it is still displaying a price of £11.99 but we assume this will be fixed shortly. Some users have reported that this piece of content is actually listed as free for them, while others aren't having such luck. It's worth trying for yourself.
So, there you have it. If you already have a copy of Mafia III, you can start playing its DLC offerings free of charge. And if you're thinking of picking the game up later on down the line, this deal will still be sat waiting for you.
